IMPROVEMENT IN GHURNS.

TO ALL WHOM IT MAY CONCERN:

- Be it known that I, WILLIAM B. McCUTCHEON, of Washington, in the Stateof Iowa, have invented a certain new and useful Improvement in Churns;and I do hereh; declare that the following is a full, clear, and exactdescription of the construction and operation of the same, referencebeing had to the accompanying drawings, and to the letters and marksthereon, which said drawings form part of this specification, andrepresent, by i Figure 1, a view, by vertical section, a churnconstructed under my improvement.

Figure 2 is a top view of the wheel-dasher of the churn.

Figure 3, a view of the wheel-dasher and perforated (lasher with a partof the shaft attached thereto; and

Figure 4 is a View of the frame supporting the power or hand-crank shaftof the churn.

, In each of these figures where like parts are shown like marks andletters are used to indicate the parts.

Tea certain extent the present invention is of the character of anadditional improvement to the churn upon which Letters Patent weregranted to me on the 11th day of September, 1866. The mechanism foroperating the dashers consists of a power-shaft, a, with a cranli, b,the shaft rotating in uprights c of a frame, at, which frame is securedto one sidie of the cover e of the churn. A bevel-toothed wheel, f, isaffixed to the shaft a, gearing into pinion g of the inner dasher-shaft7i, and also into pin'ion 't'of the outer dashor-shaft j,

which is tubular and surrounds the shaft h. A hinged bar, it, holds theupper end of the shaft 71, the lower end of which has its bearing Z on apin or pivot at m in the bottomnof the churn. The upper and lowerbearing and support of the tubular shaft j is shown in fig. 1 to be intoa plate in the cover and on a collar of the shaft 71. From this briefrecital of the parts it will readily be seen that the one dasher-shaftis rotated in the one direction, and the other dasher-shaft in theopposite direction, carrying with them their respective dashers. It willalso be seen that by elevating the hinged bar is, the shaft may beliberated from the motive mechanical means or devices, and by the takingoff of one-half of the cover that the dasher-shafts and dashers may beremoved from the churn. The wheel-dasher x is attached to the shaft 7t,and the perforated dasher to the shaft j. The perforated dasher '0 hasits faces curved in opposite directions, so that in rotation the facesof this dasher will act to force the cream down against the inclinedfaces 12 of the wheel-dashcr, while these faces 1) of the wheeldasherwill so act upon the cream as to force it under the rim 9 of the wheel,and out against the sides of the churn and thence upward to be actedupon again by the perforated dasher, and this united and continuousaction of these dashers will rapidly produce butter, and separating itwill, during the action of the dashers, keep it at the lower part of thechurn,

What .I. claim as my invention, and desire to secure by Letters Patentin churns where there are two shafts rotated in opposite directions, is

The wheel-dasher having the inclined faces on the one shaft, and belowthe perforated dasher having its inclined faces on the other shaft, thetwo being operated as and for the purposes herein set forth.

This specification signed this 31st day of January, 1867.
